Aloha and welcome to Bottled Ocean Treasures'© necklace collection featuring seashells collected exclusively throughout Hawaii.
A word of caution if you are shopping for "Hawaiian" shell jewelry - Some items found on the internet and in local souvenir and gift shops, might be labeled "Made in Hawaii" or "Hawaiian jewelry". If the item is inexpensive it was probably arranged in Hawaii using shells imported from the Philippines, Vietnam, China or India. Because authentic Hawaiian seashells are difficult to find, the limited quantity of Hawaii's colorful seashells are in demand and a bit more pricey.
